       6. A switch component comprising:
 a metallic spring plate comprising an outer peripheral edge and at least one pair of protrusions protruding from the outer peripheral edge; and 
 a cover of rubber covering at least one part of an upper surface of the metallic spring plate and comprising at least one pair of supporting portions that support the metallic spring plate, and a hollow portion that covers the upper surface of the metallic spring plate, 
 the at least one pair of supporting portions supporting the at least one pair of protrusions of the metallic spring plate and being positioned between the hollow portion of the cover of rubber and the outer peripheral edge of the cover of rubber. 
 
     
     
       7. A switch component comprising:
 a metallic spring plate comprising an outer peripheral edge and at least one pair of protrusions protruding from the outer peripheral edge; and 
 a cover of rubber covering at least a part of an upper surface of the metallic spring plate and at least one pair of protrusions protruding from the outer peripheral edge of the metallic spring plate, 
 the cover of rubber comprising a supporting portion that supports the at least one pair of protrusions of the metallic spring plate, and 
 the supporting portion of the cover of rubber comprising a groove that supports the at least one pair of protrusions protruding from the outer peripheral edge of the metallic spring plate. 
 
     
     
       8. A push switch comprising:
 the switch component according to  claim 7 ; 
 a first contact; and 
 a second contact that is positioned around the first contact, 
 the metallic spring plate of the switch component being arranged on the second contact over the first contact. 
 
     
     
       9. The push switch according to  claim 8 ,
 wherein the second contact comprises two or more contacts that are positioned around the first contact. 
 
     
     
       10. The push switch according to  claim 8  further comprising:
 a resin body comprising a first connecting metallic lead and a second connecting metallic lead, 
 wherein the first contact is electrically connected to the first connecting metallic lead, and 
 the second contact is electrically connected to the second connecting metallic lead. 
 
     
     
       11. The push switch according to  claim 8  further comprising:
 a substrate comprising an upper surface on that the first contact and the second contact are arranged. 
 
     
     
       12. The push switch according to  claim 11 ,
 wherein the substrate further comprising a first connecting terminal electrode that is electrically connected to the first contact and a second connecting terminal electrode that is electrically connected to the second contact. 
 
     
     
       13. An electronic device comprising:
 a motherboard comprising a first electrode as a first contact and a second electrode as a second contact; and 
 the switch component of  claim 7  being electrically arranged on the motherboard, the outer peripheral edge of the metallic spring plate of the switch component being arranged on the second contact of the motherboard. 
 
     
     
       14. A push switch comprising:
 a first contact; 
 a second contact being positioned around the first contact; 
 a metallic spring plate comprising a central portion, an outer peripheral edge, and at least one pair of protrusions protruding from the outer peripheral edge of the metallic spring plate, and the outer peripheral edge of the metallic spring plate being arranged on the second contact and the central portion of the metallic spring plate being positioned over the first contact; and 
 a cover of rubber covering at least one part of an upper surface of the metallic spring plate and the at least one pair of protrusions protruding from the outer peripheral edge of the metallic spring plate,
